Dynamic Heap Example in C++


Description:

The dynamic memory requested by our program is allocated by the system from the memory heap. However, computer memory is a limited resource, and it can be exhausted. Therefore, there are no guarantees that all requests to allocate memory using operator new are going to be granted by the system.

Example Program:

Here is the simple program dynamic heap in C++.

Source Code

#include<iostream>
using namespace std;
int main()
{
    int *p=new int[5];
    p[0]=10;
    p[1]=20;
    cout <<p[1]<<endl;
    delete []p;
    p=nullptr;
    return 0;
}
